Optiray 320 is used in adults for various types of X-ray procedures, including:

• vascular imaging, arteries, and veins
• kidneys
• CT scans

Optiray 320 is a contrast medium containing iodine. Iodine does not allow X-rays to pass through, enabling the visualization of blood vessels and other organs

Do not take Optiray 320

• if you are allergic to contrast media that contain iodine or to any of the other components of this medication (listed in section 6).

• if you have clinical hyperthyroidism.

Warnings and precautions

• asthma or have had previous allergic reactions such as nausea, vomiting, low blood pressure, skin symptoms
• heart failure, high blood pressure, circulatory problems, or have had a stroke, and if you are very elderly
• diabetes
• kidney or liver disease
• brain problems
• bone marrow problems, such as some types of blood cancer known as multiple myeloma, Waldenström macroglobulinemia
• some abnormalities of red blood cells, known as sickle cell anemia
• adrenal gland tumor, which affects blood pressure, known as pheochromocytoma
• an increase in the level of the amino acid homocysteine, due to abnormal metabolism
• a recent study of the gallbladder with contrast medium

• planned a study of the thyroid gland using a substance that contains iodine. This can be postponed since Optiray 320 may affect the results for up to 16 days.

Severe skin reactions have been reported with the use of Optiray, including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SSJ), toxic epidermal necrolysis (Lyell syndrome or NET), and acute exanthematous pustulosis (PEAG), which can be life-threatening.

During the imaging procedure or shortly after, you may experience a temporary alteration in brain function called encephalopathy. Inform your doctor immediately if you experience any of the symptoms related to this condition described in section 4.

Children under 18 years

Optiray 320 is not recommended in this age group

In case of exposure (direct exposure or newborns whose mothers received iodinated contrast medium during pregnancy), the thyroid function should be evaluated at birth and in all pediatric patients under 3 years within a month after exposure.

Use of Optiray 320 with other medications

Inform your doctor or radiologist if you are using or have used recently or may use other medications.

The following medications may interact, influence, or be influenced by Optiray 320:

• metformin: medication to treat diabetes

Your doctor will measure your kidney function before and after using Optiray 320. Depending on the level of your kidney function, your doctor may consider interrupting the use of metformin between 48 hours before and during the test. Do not resume until at least 48 hours later and only if your kidney function has returned to normal

• interleukin: medication to treat some tumors
• some medications to increase blood pressure due to narrowing of the blood vessels and to prevent any risk of nervous system disorders. Optiray should never be used while using these medications
• general anesthetics

High-frequency adverse effects have been reported

• diuretics:medications that increase urine production and decrease blood pressure.

In case of dehydration caused by the use of diuretics, the use of iodinated contrast media may increase the risk of acute renal failure.

Use of Optiray 320 with food and beverages:

Limit food intake before the test. Please consult your doctor if you have any doubts. If you have kidney disease, do not limit fluid intake as it may reduce kidney function.

Pregnancy and breastfeeding
